I modified your application so that it has a client and a server webapp. It works great.
Then I modified it so that it works with JNDI, the server application does not seem to issue a reply whereas when I check the activemq mysql database, I see those messages sent from the client side. It does not seem to work… Thanks for suggestions.
Here are my config files:
web.xml:

ActiveMQ JMS Connection Factory
jms/ConnectionFactory
org.apache.activemq.ActiveMQConnectionFactory
Container

ActiveMQ request Queue
jms/requestQueue
org.apache.activemq.command.ActiveMQQueue

ActiveMQ reply Queue
jms/replyQueue
org.apache.activemq.command.ActiveMQQueue

context.xml:

shared-context-jndi.xml:

org.apache.activemq.jndi.ActiveMQInitialContextFactory

requestQueue
replyQueue

java:comp/env/jms/ConnectionFactory

requestQueue

replyQueue

how do I configure tomcat with activemq connection factory so that I can use jndi based factory to use the queues/topics?

MDP's rule!! But can you explain why we need concurrent-1.3.4.jar and geronimo-spec-j2ee-management-1.0-rc4.jar on the classpath

Seems like it is required by ActiveMQ. I got this application running with ActiveMQ 4.1 without any problem, and I didn't included those two jar files. All the classes of those two jar's were inside the ActiveMQ 4.1 distribution jar file.

Great article !!

Is there anyway to use MDPs to communicate with components of a application through firewalls?

Thanks.

I have this example working now - by starting activeMQ from it's install folder. However, I now want to embed the start-up of it by setting . From my understanding, if I do this, all I'd have to do is start the server and then the client. And activeMQ should be started up automatically. This isn't working for me though. Maybe someone could explain what's going on in the background and what I'm doing wrong here .
Thanks

I am using websphere mq and webspehere appserver to run my spring app. I have connection factory (type com.ibm.ejs.jms.JMSQueueConnectionFactoryHandle) configured in websphere appserver and a destination Q (type com.ibm.mq.jms.MQQueue) configured in websphere appserver.
These are exposed as jndi's to my app.

My config looks like this (doesn't work - am not sure what bits I am missing)

How do I change the above configuration to expect the JMSQueueConnectionFactoryHandle and com.ibm.mq.jms.MQQueue types? Can you please guide?

Sorry quoting doesn't work…

Just replace org.activemq.message.ActiveMQQueue with org.apache.activemq.command.ActiveMQQueue
and org.activemq.ActiveMQConnectionFactory with org.apache.activemq.spring.ActiveMQConnectionFactory
